...essure in the interior chamber of the eye, killing fibers in the optic nerve. Glaucoma patients go to the doctor periodically to have their eye pressure checked. If it is high, the doctor prescribes medication or performs surgery. "The problem is that your interocular pressure spikes over hours, sometimes...

...the deterioration of myelin, which insulates nerve fibers and enables them to properly conduct impulses in the spinal cord, brain and peripheral nervous system throughout the body. The findings suggest that LPC causes sheath degradation by allowing an influx of calcium ions into the myelin. The increased ...

To peer into the normal developing brain, the investigators sought children from diverse geographic, socioeconomic and ethnic backgrounds. They recruited children from six sites across the U.S.: Children's Hospital in B...

...e motor nerves are bigger, while the sensory nerve fibers are smaller," he said. "When the nerves are trying to regenerate using a motor nerve as a graft, it's easier for them to use the larger axons of another motor nerve, although the reason why is not clear." The results could eventually translate into...

However, Balcer said the potential benefits of natalizumab treatment must be weighed with the drug's potential risks or complications, including the rare, often lethal brain disease progressive multi...

...on loss due to inflammatory demyelination of nerve fibers that connect to the eye, a common cause of visual loss in MS," says Laura J. Balcer, MD, MSCE, Associate Professor of Neurology and Ophthalmology at Penn, and lead author of the paper. The researchers analyzed data from two randomized, double-bli...

Psyllium, pectin, and guar gum are other soluble fibers that work similarly. 5-HTP (5-Hydroxyl-L-tryptophan): Due to high-stress, many people in America have low levels of serotonin, a brain chemical that controls appetite and mood. The result: overeating. 5-HTP is a natural amino acid that boosts s...

Poisoning with botulinum toxins leads to an often-fatal paralysis, which is one reason they are considered among the highest biodefense research priorities by the U.S. government.

...s system (CNS). In MS, the myelin coating of nerve fibers becomes inflamed and scarred. As a result, messages cannot be sent through the nervous system. Dr. Rostami, who is also director of the Neuroimmunology Laboratory in the Department of Neurology at Jefferson Medical College, and his group used an a...
